Relativistic rotation and classic electrodynamics validity limit

As it is known the limit of applicability of classical electrodynamics (ED) is limited with so called electron´s classical radius Rcl∼elmc². This estimation appears in the several totally different approaches to the problem with one common assumption, that electron has a finite size. It is necessary to specify that there is no consecutive and strict account of the relativistic rotational movement´s contribution into the calculation of energy and angular momentum of the researched objects. Such omission is that the contribution in cross section of EM waves scattering on the magnetic moment of electron can be neglected, while it is not correct for relativistic velocities. In this paper it is shown that the removal of such omission (in the context of strict relativistic description) leads to the possibility of obtaining the correct limit of applicability of classic Rcl∼h/mc.
